Abstract

The invention discloses a data communication method. The method comprises the following steps: receiving a connection request sent by a client; judging whether the connection request is a third handshake request or not; if so, sorting the data packet information of each client through a preset rule to obtain a credibility queue; and sending the credibility queue to the server, so as to enable theserver to perform data communication with the client corresponding to each piece of data packet information on the credibility queue according to the descending order of credibility. According to themethod, the proxy server is arranged to sort and optimize the connection requests of the client according to the preset rule, so that the SYN Timeout time is greatly shortened, a large number of semi-connection requests are directly discarded or blocked, and the SYN flooding attack is effectively resisted. The invention also provides a data communication device, a proxy server and a readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of data communication, in particular to a data communication method, device, proxy server and readable storage medium. Background technique [0002] Strictly speaking, a DDOS attack is a technical method of destroying network services. There are various specific implementations. Its fundamental purpose is to make the victim host or network unable to receive and process external requests in time, or unable to respond to external requests in time. In severe cases, the device will crash and the network will be paralyzed. [0003] The Synchronize Sequence Numbers (SYN) flood attack is a kind of DDOS attack. This attack mainly uses the three-way handshake information during the TCP connection. The attacker maliciously sends many TCPSYN packets to the server quickly and continuously without any When subsequent confirmation packets are sent out, the TCP connection queue available on the server will exceed its allo...
